Need a better fit? Learn how the Quatro Adjustable Socket is designed to provide a secure, adaptable fit for people experiencing discomfort, looseness, pressure, or daily limb volume changes.

Why Socket Fit Matters

A prosthetic socket connects the body to the prosthesis. When the fit changes throughout the day, users may experience discomfort, pressure, or reduced confidence. Quorum’s adjustable socket technology is designed to help address these everyday challenges.

Socket fit matters because it helps support comfort throughout the day by accommodating natural limb volume fluctuations.
Socket fit matters because a more secure fit can help reduce unwanted movement within the socket.
Socket fit matters because personalized care supports the unique needs of each individual.
Socket fit matters because it supports mobility, stability, and confidence during daily activities.

DIGITAL DESIGN

We use advanced scanning and CAD modeling to design patient-specific solutions with precision and consistency.

ENGINEERING

Our engineers refine each design for fit, function, strength, adaptability, comfort, durability, and performance.

3D PRINTING

3D printing allows us to fabricate custom sockets, panels, and components with complex geometry and repeatable quality.

TESTING & VALIDATION
